<p>Obviously I am going to have to get inside it. I had hoped that
maybe when I had to replace the little regulator that works in the
first stage that maybe it needs more pressure to keep the vanes
from chattering. In rotary vane refrig compressors, back pressure
keeps the vane against the rotor. In this case, the vane rotates
and the center of the rotor would have to be the pressurized
side. The sump is about 30 gallons.<br>

<p> An update on the compressor problem. I received a post on
Smokstak from a former owner of a smaller Inger soll
compressor who stated that this occurred on his unit just
before the compressor end failed and he could not get parts so
he junked it... I cannot afford to let this one get junked,
so I am trying to find out what to look for. Last year when
running at idle I would hear something like a dry bearing
squeal, but could find nothing out of the ordinary. I
remember Bo Hinch telling me that he used to make the vanes
for these compressors and nearly everything could be re-made
on them from a machine shop.</p>

<p>This is a little off topic, but I use this compressor to
blow out my hay equipment before putting it back in the
shed, and also to blow out the radiators. It is a
Ingersoll Rand VAne Type compressor 250 cfm powered by a
4-53 Detroit diesel. When the compressor build back up and
the engine begins to idle down it makes a loud clicking
sound. I cannot determine if it is a rod knocking or maybe
valve related. I know Bo Hinch had a lot of experience with
these engine compressor combinations. I don't think the
compressor is making the noise. I had some knocking in the
engine a couple of years ago when I changed the oil and used
15W-40 Mystic. I changed over to 40W Mystic and it stopped
the knocking, but now the loud click. I cannot afford for
this machine to be down if we ever get a hay crop to bale.
My baler has to be blown out every day or the belts bind up
with chaff and stop. <br>
